摘要： A continuously variable transmission steering mechanism of a tracked vehicle, comprising a differential (1), a right drive shaft (2), a left drive shaft (3), and a continuously variable transmission (4) used for adjusting the rotational speed of the right drive shaft (2) and that of the left drive shaft (3). A left half shaft (5) and a right half shaft (6) are connected on the differential (1). The right half shaft (6) of the differential (1) is linked to the right drive shaft (2). The right drive shaft (2) rotates to drive the right half shaft (6) of the differential (1) to rotate. The left half shaft (5) of the differential (1) is linked to the left drive shaft (3). The left drive shaft (3) rotates to drive the left half shaft (5) of the differential (1) to rotate. The rotational speed ratio of the right half shaft (6) of the differential (1) to the right drive shaft (2) is equal to the rotational speed ratio of the left half shaft (5) of the differential (1) to the left drive shaft (6). The employment of the continuously variable transmission steering mechanism of the tracked vehicle, by means of continuously and precisely adjusting the rotational speeds of the left and right half shafts of the differential via the continuously variable transmission (4), implements precise turning of tracks, thus increasing the safety of the tracked vehicle traveling at a high speed.
